I liked the part where he neglected to mention any possible benefit of the current arrangement or the fact that many of us have no problem with actually being required to type well and remember stuff.
Typos happen even to those who can type well. And I can remember my password, but sometimes it's a matter of figuring out which password to remember. If the one I expected to work doesn't, it just be that I unknowingly mistyped it, not that it was the wrong password.
